Wouldn't we expect to see substantially more than 30% of the DNA be different.

I don't think carbon dating can be used to extract DNA.

I also would have thought DNA would have degraded significantly over that period of time.

There are probably a thousand more reasons this is blatantly false, to those with scientific knowledge beyond my early highschool experiences.

It's bizarre and fascinating the Mexican government has entertained this.

It is like a highschooler tried to makeup a convincing story. If they had DNA it would have been sequenced and the code shared the next couple days. It would have been THE BIGGEST find in molecular biology, ever.

All that happened is some idiot Senator invited some idiot scammer to give a talk about his scam. I don't think they really had to "entertain" it and it has no legitimacy.

But he testified under oath!

According to witnesses at the hearing he also “crossed his heart and hoped to die”

There are (~conspiracy) theories out there for hybridized/synthetic human-alien biologies, so it's not completely unexpected or unprecedented discourse in the UFO world.

Humans share ~60% DNA with fruit flies, so the reported ~70% similarity seems quite low for such a "quasi-human" figure.

Perhaps you could make a case that DNA retrieval from such an old sample would be corrupted. It does seem more like the figure is tuned by the exigencies of pop-sci click bait.

Anyways they shared the full sample online, so legit geneticists could potentially weigh in.

The DNA difference is likely mostly due to failed sampling and lack of good data in existing databases

It's not outside the realm of possibility that life on earth might have been seeded from other alien life either intentionally, or by viruses or bacteria hitching a ride on meteorites.
